Abstract: A charge calculation apparatus includes: a consumed amount acquisition section that acquires an amount of a consumable consumed for printing in a first period; a carried-forward amount calculation section that calculates a carried-forward amount of the consumable on a basis of the consumed amount and a base amount of the consumable for the first period; and a charge calculation section that calculates an amount of money charged for printing on a basis of the carried-forward amount. The consumed amount acquisition section acquires a second consumed amount that is an amount of the consumable consumed for printing in a second period that is posterior to the first period. The charge calculation section calculates the amount of money charged for the second period on a basis of the second consumed amount, a second base amount that is a base amount of the consumable for the second period, and the carried-forward amount.
